Application filed September 17, 1912.

To all whom it may concern:

Be it known that I, Murrow M. lll umonv, a citizen of the United States,residing at Springfield, in the county of Lane and State of Oregon haveinvented new and useful improvements in Swings, of which the followingis a specification.

'.l.he general object of this invention is the provision of a swinghaving a driving mechanism connected thereto which is adapted for movingthe swing longitudinally of suitable tracks; and to this end theinvention consists of certain novel arrangements, constructions andcombinations of devices which will be described hereinafter and thenpointed out in the appended claims.

in carrying out the object of the invention generally stated. above, itwill be under stood, of course, that the essential features thereof aresusceptible to changes in details and structural arrangements, onepreferred and practical embodiment being shown in the accompanying drawings, wherein:

Figure 1 is a side elevation of the swing and track support therefor.Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is an endelevation of the swing, the tracks being shown in section. big. a is atop plan view of the swing showing the mechanism for driving the sameupon the track.

Referring more particularly to the accompanying drawings in which likereference characters designate similar parts, it will be seen that theinvention comprises a plurality of oppositely disposed uprights whichare srupportcd by me: as of the lower braces 6 and upper braces 7, saidsupports being connected longitudinally by means of the tie rods ortrusses 8 and transversely, by means of the beams 9. Depending from thebeams are a plurality of track hangers 10 which are adapted to havesecured thereto the oppositely disposed tracks 11 which are preferablymade of suitable metal and which are bent into substantially ll-shapeand provided at free edges with the inturned flanges 12 for preventingdisplacement of the wheels of the truck to be presently described. Thetracks 11 are preferably given a. wave formation whereby the same areprovided with a plurality of upward and downward inclines 13 and 121-.respectively.

The carrier or truck comprises a frame 15 preferably rectangular information and. made of any suitable material, said frame havingjournaled adjacent the ends the Specification of Letters Patent.

transverse axles 16 and 17, each shaft carrying the wheels 18 which areadapted to engage the tracks 11 whereby the truck is supported thereon.The axles 16 and 17 also have mounted thereon the cog wheels 19 whichare adapted to engage the rack teeth 20 formed upon. the lower flanges12 of the tracks 11, said rack teeth being formed only upon the upwardinclines 13 of said tracks, whereby the upward movement of the truck orcarrier upon said inclines is facilitated. The longitudinal sides of theframe 153 also have journaled therein intermediate the ends thereof acranl: shaft 21 upon which is fixed a wheel 22 adapted to mesh with thepinion 23 carried by the axle 16. The shaft 21 is driven through themedium of a plurality of driving'rods .24 which are connected to saidcrank shaft 21 and also connected at their opposite ends to the uprights25 of the swing 26, the upper ends of said uprights being pivotallyconnected to the frame 15 in. any suitable manner. "it is to beunderstood that the swing 26 may be of any usual construction andfurther description thereof is therefore deemed unnecessary.

It is to be understood that the tracks 1.1 may be endless and arrangedin circular formation or may be straight and in either case it will beseen that when persons enter the swing 2(5 and rock back and forth,motion will be imparted to the driving rods 21: through the medium ofthe uprights of said swing and said drive rods will cause the crankshaft 21 to rotate thus imparting a similar movement to the aXle 16whereby sufliciei'it power will be imparted thereto in order to propelthe truck or carrier up the inclines 13. Sufficient inon'ientiiun willalso be imparted to the truck or carrier when the same is on thedownward inclines 1-1: to facilitate the upward movement of the saidtruck or carrier and hence it will be seen that the swing will attain aconsidiurable speed in moving over the tracks.

From the foregoing description taken in connection with the accompanyingdrawings, it will. be seen that the invention conten'nplates providinga. swing which is comparatively simple in construction thus reducing thecost of manufzmtlu'e of the same to a minimum and. which is durable andeffective in carrying out the purpose for which it is designed.

What is claimed is 1. The combination with a plurality of from saidtruck and adapted to drive the latter longitudinally of said tracksthrough the medium of its swinging movement.

2. The combination with a plurahty of uprights, and track supportscarried thereby, of tracks depending from said supports,

a truck including wheels adapted to travel upon said tracks, a swingdepending from said truck and adapted to drive the latter longitudinallyof said tracks through the medium of its swinging movement, and adriving mechanism carried by said truck and adapted to be operated bysaid swing.

3. The combination with a plurality of uprights, of a plurality oftracks supported by said uprights, each of said tracks comprisingsubstantially U-shaped beams having inturned retaining flanges at theirfree edges, a truck including wheels adapted to travel upon said tracks,a swing depending from said truck, and a driving mechanism 25 carried bysaid truck and connected to said swing whereby the latter is movedlongitudinally of said tracks through the medium of its own swingingmovement.

1. The combination with a plurality of uprights, of tracks carried bysaid uprights, said tracks constructed in wave formation to provideupward and downward inclines, rack teeth carried by said upwardinclines, a truck including wheels supported by said tracks, a drivingmechanism including gear wheels adapted to engage said rack teethcarried by said truck, and a swing depend ing from said truck andadapted to operate said drive mechanism.

In testimony whereof I aflix my signature in presence of two witnesses.
